摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of vibration through the lowering of lockup capacity during coast lockup and to regulate the degree of the lowering of capacity to a constantly proper value. SOLUTION: During a time between a moment t1 at which a foot parts from an accelerator pedal in a lockup region and a moment t2 when a given time ΔT elapses, a lockup clutch fastening differential pressure PL is lowered to a given differential pressure PLS for vibration prevention. Thereafter, the fastening differential pressure PL is gradually increased at a time change gradient αaccording to a throttle opening TVO. The given differential pressure PLS is determined by adding the differential pressure correction value ΔPL to a differential learning value PLE being the very limit at which a torque converter is prevented from the occurrence of a slip in a coast lockup state. By adjusting the differential pressure correction value ΔPL to a value corresponding to a car speed and the number of revolutions of an engine just before the starting of control of a differential pressure, coupled with the differential pressure value PLE, prevention of the generation of vibration during coast lockup and responsiveness to the re-increase of the differential pressure PL are made compatible to each other at a high order.
